' I Application filed. my 4, 1920. Serial No. 106,634.

This-invention relates to wrecking cars of the class where the wrecking eqmpment 1s 'mountedfon an automobile body and the 1nvention has for its objects a special arrangement of wrecking hoist elements adapted for mounting on and cooperating with a com-- mon runabout type, or passenger car chass1s,

1 for effectively using the power of the autoa special hoist frame, hoist drum and control, mounted at the rear .end of. the chassis of an automobile operatively connected to its propeller drive shaft, and the lnstallation of a clutch between said shaftand the hoist for control at the rear end of the chassis, togetherwith additional means at the rear end of the chassis for throwing the regular clutch of the automobile.

Besides the above, the invention includes special control of the hoist drum at the rear end. of the chassis and a frame mounting adapting the device to meet most all condltion found in salvaging wrecked automobiles,

" especially such as have gone over the bank.

The drawings accompanying this application show my-improved wrecking car in its preferred form, though it is to be understood that such changes as come within the spmt :20 of the invention are intended to be covered in the claims.

In the drawin Figure 1 is a sideelevation of my wrec 'ng car as it would appear going to a job with boom elevated.

Figure 2 shows the rear end of the] car with boom lowered to the ground and held against displacement by means of a. stake driven in the road. I

Figure? is a 'plan of a hlghway with my car in position with' boom anchored as in Figure 2 and with rope extended down .embankment to salvage wrecked car.

Figure 4 1s a general plan, of the transmission elements shown in their relation to the chassis of the automobile.

Figure 5 is an enlarged end view of the drum unwinding control, and Figure 6 is an enlarged view of one of the adjustable feet under the hoist drum.

In further detail the drawings show at 1 an automobile 'to the frame 2 of which is secured at the rear end a pair'of L shaped extensions 3 supporting a shelf 4 on their lowermost portions," while above the shelf is r a shaft 5 revolvably carried in bearings 6 secured to the extensions 3. f

Secured to the shaft 5 is a 'hoistdrum 7 on which the rope 8 is wound and the free end. of' which rope extends over'a block 9 earned at the outer end of a boom 10.

ported on the shaft 5 for lowering'to various angles, and it is held in upright position by a pair of guy ropes 11 extending from the central part of the automobile and hooked to any of the rings 12.

At one end of the drum is a large sprocket '13 connected by a chain 14 to a small sprocket 15 onca countershaft 16 revolvably mounted on the frame 2, and a large bevel gear 17 also secured to the shaft 16 meshes. with a bevel pimon' 18 carried on a longitudinally extending shaft 19 revolvably supported by the frame 2 and carrying on its forward end PiA TENT OFF CE.

The boom comprises an A shapedframe, preferabl of large diameter piping, and the lower en s of the frame are pivotally supa large sprocket 20 connected by a chain 21 to a small sprocket 22 mounted on the engine shaft 23 forward of the transmission gears 24., The sprocket 22 is'free on shaft 23, being' held from longitudinal shifting by collars or equivalent as at 25 and has clutch teeth formed'onone side ada ted to mesh with a jaw clutch 2e slidably feathered on of the vehicle. The unwinding of the drum is controlled by means of a special brake band arrangement shown in Figure 5, the band 33 being pivotally anchoredat 34 to the shelf and after extending almost the full circumference of a braking flange 35on the drum is resiliently pulled down by a spring the circumference of t matically. release in winding the drum in the direction of the arrowin lpulling a load but will more tightly grip t e band upon attempting reverse direction, and consequently '36, thus the band overlyingi more than half e ange will autowill hold the load at any point upon ting E the winding power.. -'To release the load for controlled unwinda spring 39 in aing ofthe Zope,the-band 33 is slackenedloff by means band .at 38 and normally pulled by means of direction to tighten the f a hand lever 37'linked'to the band. .When hoisting a load the pressure is taken from the main road springs of the vehicle by a pair of adjustable feet 40 which are placed against the highway, the roller 40 permitting shifting of the vehicle with slidable through frame of the shelf 4, and provided with a hoist loaded.

Figure 6-shows the prefer-relconstruct on of the feet, each comprising yertlcal pipe a collar 41 secured to the series of holes 42, into which a in. 49 is I inserted through a hole in the collar,"and

having a wide rimmed roller 4&0 mountedat the lower end adapted to transfer: the pull of the common vehicle'springs.

driven to the of hoisting to the ground at a point rear In operation, the vehicle 15 scene of the wreck with hoist frame elevated as shown inFigure 1, and if a mere hoisting ob is 1 angle, as per dotted position A-in Figure 2,,

required the boom is given a proper by hooking the guy ropes 11 in the various V. road as shown in Figure 2 the easiest way rings12. If a wreck must be pulled up an embankment, the-boomis lowered to the J to accomplish this'being to engage the lift- 1 ing hook 43 with the-transverse brace 47 of the boom and permit the drum to unwind by releasing the drum control lever 37. The lowered end of the boom .is suitahly roadway, or if desired the stake may be driven in the earth beyond the roadway as at44', and connected by a cable or chain 48 f to the end of the boom.

. The use of a stake in the manner described overcomes the danger of pulling the. carout of place when hauling on a wreck as at 45 to get the same up from a gully,-as

I it puts the strain directly on the stake.

Before operating the hoist the transmission of the car is put into neutral so that the drive shaftforward of-this point is 'rotating'under power of engine 46 without driving the vehicle, and to start the hoist,

the regular clutch of the car is thrown out by means of hand lever 30 and the hoist mechanism engaged by operating the sprocket'clutch lever 29, after which the car clutch may be'let inslowly to start the load. To

' disengage the load either clutch may be thrown out, though the car clutch is; the j easiest to operate under heavy load reaction tending to hold it t for attaching the guy ropes. Thespeed of the hoist The rope extending anchored by means of a stake 44 driven n the there is no engaged. V j I The boom may be lifted from the ground by engaging, the hoisting hook with the brace rod 4:1 and upon gently'starting the hoist drum the boom-will rise to a position is controlled by the-speed of the engine through the usual throttle of the vehicle not shown, but which is set at any-intermediate speed at which the unwinding of the drum.

1. An automobile wrecking car provided with extensions at the rear end of the chassis frame, a hoisting drum mounted on said extensions geared through. a plurality of transmission elements to the engine of the vehicle, and a hoisting boom pivotally.

mounted at the rear of the vehicle on said extensions adapted for lowering of its. outer end to the ground. 1

2. An automobile wrecking car provided pulling as i with extensions at the rear end of the chassis frame, a hoisting drum mounted on said extensions .geared through a plurality of transmission elements to the engine ofthe vehicle, a hoisting boompivotally mounted on said extensions adaptedfor lowering of its outer end to the ground, and means for raisingsaid boomthrough actuation of said drum. 1

In a structure as specified 'in claim 1, a pair "or ground wheel supports for the rear end of the vehicle slidable vertically through guides,and means for locking said,

supports in adjusted position.

4;. An automobile wrecking'car provided Withhoisting. elements including a rope drum mounted at 'the -rear end thereof, transmission elements connecting the rope drum foroperation by-the vehicle engine and including a jaw clutch for engaging a powerrshaft of said engine, a hand lever for operating said clutch positioned at the rear end of the vehicleaccessible to an operator on the ground, and an adjacent lever connected for operatlng the main engine clutch of thevehicle.
